New Features & Style

I've needed this script for a few different projects and figured I should share my modifications. If I may be so bold, I've dubbed it v0.3.1. 

Here are the features I've added:
    - Added new Carousel style! Shows 5 items at a time in a looping carousel
    - Added `itemContainer`, `itemSelector`, `style`, and `start` options for basic configuration
    - Added `enableKeyboard`, `enableMousewheel`, and `enableTouch` options to enable/disable features
    - Added `enableNav` and `enableNavButtons` options to insert controls into the container
    - Added `onItemSwitch` callback
    - Better Demos to showcase the new features

You can see the live demos here: http://brokensquare.com/Code/jquery-flipster/demo/

The script is still lightweight, but could probably be optimized a bit more. I've needed the Carousel style the most in my implementations, but you could easily cut the filesize down by taking it out if you don't think it's essential.

Feel free to modify how you see fit!
